As we know, in 2016, Shennongjia made it onto the UNESCO World Heritage List. UNESCO 1. awarded (award) Shennongjia this status because it meets two criteria required by the list. For the first criterion, Shennongjia is 2. apparently (apparent) one of the most "complete" natural areas in the world. Its broad region in altitude leads to a great variation in climatic conditions, which allows a wide 3. variety (various) of species to thrive. For the second criterion, Shennongjia has over 3,000 plant species, 4. representing (represent) more than ten per cent of China's total floral richness.
It is a challenge to look after so many species. Thanks to those 5. scientists' (scientist) efforts, the monkey's population has doubled 6. since the 1980s. But the most 7. impressive (impress) aspect of Shennongjia is the local people, 8. who take things from nature without causing damage. By providing the bees 9. with a secure home, the villagers collect their honey in return. All of this explains 10. why Shennongjia earned—and deserves—its place on the list.

答案： 1. awarded 2. apparently 3. variety 4. representing 5. scientists' 6. since 7. impressive 8. who 9. with 10. why

Where were the dull sounds of flying insects hitting against the light bulb? Even the absent singing of cicadas or crickets, whichever they were, had quieted its instruments. Where have all the insects gone?
Our own existence depends on a diverse insect world. Studies show that where more insect species are present, pollination (授粉) is more reliable. As Dave Goulson, professor of biology, points out in his book *Silent Earth: Averting the Insect Apocalypse*, about three-quarters of all crops grown by humans require pollination by animals, the vast majority by insects. "We could not feed the global human population without pollinators," he writes. It's not just about bees and butterflies, the beautiful insects. Other, less visually appealing pollinators such as flies, moths, and earwigs are also showing declines. Several of these species don't just pollinate. They also eat the pest (害虫) insects that ruin crops.
It turns out that ecologists and entomologists around the world have been warning about declining insect numbers for years. The culprits are climate change, habitat loss, light pollution, intensive farming, pesticide and fertilizer use.
But it's a struggle to get people to act. After all, we humans have a complicated relationship with our six-legged fellow companions. Who can forget the horror of Kafka's *The Metamorphosis* (《变形记》), where a travelling salesman wakes up one morning to find himself transformed into an insect? Even insects like butterflies and bees can seem strange when you look at them closely. Maybe we've been ignoring them because they seem different from us.
Some steps may be as simple as turning off artificial light. A recent study in China found that trees in Beijing, lit by street lights at night, seem to have tougher leaves. In other words, insects are probably being starved in the area.
We should change our attitudes to insects. Those annoying flies hovering around your food are simply doing what they were born for. They're recycling. Without them we might be wondering what to do about rotting (腐烂的) waste. Besides, they're food for birds, and UK bird populations have greatly decreased in recent years.

C. Insect pollination affects the crop types.
D. Insect decline threatens global food supply.
2. What does the underlined word "culprits" mean in Paragraph 3?
A. Solutions.
B. Causes.
C. Effects.
D. Consequences.
3. 新考法 What is the author's purpose in writing the text?

B. To compare the different features of insects.
C. To warn about the insect decline and its effects.
D. To review the history of human-insect relationship.

答案： 语篇导读 本文是一篇说明文。文章以昆虫数量减少的现象开头,引出昆虫对生态系统和人类生存的重要性,并指出昆虫数量下降是由于气候变化、栖息地丧失、光污染、集约化农业、杀虫剂和化肥使用等因素造成的,并强调了人类对昆虫的态度需要改变。 1.D 细节理解题。根据第一段"Where were the dull sounds of flying insects hitting against the light bulb? Even the absent singing of cicadas or crickets, whichever they were, had quieted its instruments. Where have all the insects gone?"和第二段中的"Our own existence depends on a diverse insect world...'We could not feed the global human population without pollinators,' he writes."可知,文章引出昆虫数量下降的现象,并且重点说明了昆虫对人类食物生产的重要性。并强调没有授粉者,我们无法养活全球人口。这表明昆虫数量下降威胁着全球粮食供应。故选D。 2.B 词义猜测题。根据上文"It turns out that ecologists and entomologists around the world have been warning about declining insect numbers for years."可推测,下文指出了昆虫数量下降的原因是气候变化、栖息地丧失、光污染、集约化农业、农药和化肥的使用。culprits指的是这些导致昆虫数量下降的因素,也就是"罪魁祸首",即"原因",和causes同义。故选B。 3.C 推理判断题。文章从昆虫数量减少的现象开始,并重点阐述了昆虫数量下降的原因以及对生态系统和人类生活的影响。作者通过一系列论证,呼吁人们重视昆虫的价值,并采取措施保护昆虫。因此,文章的目的是警告人们昆虫数量下降及其影响。故选C。
